I was thinking about a backstory for an object and tried to come up with guys that would want to steal it, I'll spare you the details but basically consider this: A group which opposes the Foundation's1 research into the occult, believing it to be bad. It would be like the SH mixed with the CI but with the lack of coherent motive as a bug not a feature. Now I haven't done much drafting with them yet because that would require me getting off my ass and posting something but it seems very useful for narrative reasons. It would both be understandable and usable as a disruption to Foundation operations.

The "greater good" the Foundation and other groups are attempting to achieve is simply not worth it.

The more theological member think:

God intended humanity to stay animalistic.

Humanity's intelligence was cause by and entity that opposes God, Possibly the CotBG's deity or the Serpent from the Bible.

Anything created through science and/or mathematics is "unnatural" and blasphemy.

If they bring upon a mass-intelligence-failure scenario humanity will be able to re-unite with God.

Humanity gained the capacity for evil along with the capacity for thought and would lose the ability to sin if thought was removed.

It would also have the narrative purpose of bringing most GoIs together should the story demand it2 except for maybe the GOC and Factory. You know enemy of my enemy kinda thing, even the CI should hate these guys if SCP-001: "The Children" is any indication. People would finally (hopefully) be able to get rid of the generic cackling evil tropes that the CI and SH have.

It also would massively help the world-building of the Foundation-verse considering there's actual groups like this just with mundane sciences. Though I should warn you: be prepared if you look into it because one specific racist cult comes to mind so trigger warnings 'n all.

I mean, we can't give you all too much with the GOI in general. To me at least, it sounds somewhat interesting. Possibly you could link it with the Scarlet King (with it being the "God" you have talked about). I don't personally know any GOIs that use this specific premise (though I would read up some more. I am in no way an expert on GOIs), so it could create some interesting opportunities for some articles. Just remember to check the bottom of the GOIs list to check the requirements for making a GOI.

On the surface, this seems like what GOC used to be but it kind of developed later on. Obviously the more metaphysical bits are not.

It's also not clear what they want they want to with anomalies. Containment? That's Foundation. Destruction? Supposed to be GOC, not so much any more. Ignore them? We (and they) know that's entirely foolhardy.

The broader issue I have here is that (at least, depending on the writer) the Foundation is primarily containment, rather than study. You would also need a broad for a) how these people come to know about the anomalous and b) why they abhor it.

The French branch has something kind of like this— the GOI SAPPHIRE/SAPHIR, which opposes all superstitious/religious activity. Essentially, they're militant atheists, and they're on the Foundation's radar due to using "Singularities" (their word for anomalies) to combat irrationality, from a holy book that turns creationists into dinosaurs to an effort by them to un-flatten the world. They are insane.
